I have played around with this for a bit and absolutely love it. What I do like about this tool is the simplicity along with being very powerful. There are other super complicated tools which needs a lot of learning about rankings & seo etc.

However the premise of this tool is extremely simple. When I want to optimise my listing against certain keywords, how can I ensure that my listing copy has the best possible coverage for various keywords. The "hide keywords which have an exact match" is a life saver feature as it only shows a set of keywords where my content is not going to match. Optimising the text copy based on that is quite easy after that.

The ability to upload a CSV list ( can get one downloaded from Brand Analytics report ) is also helpful as I can verify my listing against actual search data.

This is quite powerful but very simple to use for my listing VA's who are good at writing English but not trained for complex SEO tools. I can just tell them to ensure that all the keywords are in the copy and tweak it to get maximum coverage.

Absolutely brilliant tool. Highly recommended if you are selling on Amazon or plan to sell in the future.
